Houdini · Last updated 9 August 2026
Houdini lets you create simulated trading agents by describing a strategy in your own words. All trading in the app is simulated — Houdini does not connect to a brokerage and never handles your money.
We do not collect analytics, advertising identifiers, location, or contacts. Houdini contains no advertising or analytics software.
To sign you in, to run your agents and show you what they did, and to keep the service working. We do not sell your information or use it for advertising, and we do not track you across other apps or websites.
We use third-party providers to operate Houdini — for authentication, cloud hosting and storage, AI processing of your strategy, and market data. They process your information only as needed to provide those services. The strategy you write is sent to an AI provider so your agent can make its simulated trading decisions.
We keep your data while your account exists. Deleting a portfolio removes its agent, trades, history, and strategy. To delete your account and everything associated with it, email tradehoudiniai@gmail.com.
Data is encrypted in transit and at rest. No system is perfectly secure, and we cannot guarantee absolute security.
Houdini is not intended for anyone under 13, and we do not knowingly collect information from children.
We may update this policy. Changes are reflected in the date at the top of this page.
